Mandatory Actions by Water Suppliers
 The term “urban water supplier,” when used in this section, refers to a supplier that meets the
definition set forth in Water Code section 10617, except it does not refer to suppliers when
they are functioning solely in a wholesale capacity, but does apply to suppliers when they are
functioning in a retail capacity.
 To promote water conservation, each urban water supplier shall implement all requirements
and actions of the stage of its water shortage contingency plan that imposes mandatory
restrictions on outdoor irrigation of ornamental landscapes or turf with potable water.
 As an alternative to the above requirement, an urban water supplier may submit a request
to the Executive Director for approval of an alternate plan that includes allocation-based
rate structures that satisfies the requirements of chapter 3.4 (commencing with section
370) of division 1 of the Water Code, and the Executive Director may approve such an
alternate plan upon determining that the rate structure, in conjunction with other measures,
achieves a level of conservation that would be superior to that achieved by implementing
limitations on outdoor irrigation of ornamental landscapes or turf with potable water by the
persons it serves to no more than two days per week.
 To promote water conservation, each urban water supplier that does not have a water
shortage contingency plan or has been notified by the Department of Water Resources that
its water shortage contingency plan does not meet the requirements of Water Code section
10632 shall, within thirty (30) days, limit outdoor irrigation of ornamental landscapes or turf
with potable water by the persons it serves to no more than two days per week or shall
implement another mandatory conservation measure or measures intended to achieve a
comparable reduction in water consumption by the persons it serves relative to the amount
consumed in 2013.
 In furtherance of the promotion of water conservation each urban water supplier shall prepare
of each month a
th
and submit to the State Water Resources Control Board by the 15
monitoring report on forms provided by the Board. The monitoring report shall include the
amount of potable water the urban water supplier produced, including water provided by a
wholesaler, in the preceding calendar month and shall compare that amount to the amount
produced in the same calendar month in 2013.

Beginning October 15, 2014, the monitoring report shall also estimate the gallons of water per
person per day used by the residential customers it serves. In its initial monitoring report,
each urban water supplier shall state the number of persons it serves.
 To promote water conservation, each distributor of a public water supply, as defined in Water
Code section 350, that is not an urban water supplier shall, within thirty (30) days, take one or
more of the following actions:
 Limit outdoor irrigation of ornamental landscapes or turf with potable water by the persons
it serves to no more than two days per week; or
 Implement another mandatory conservation measure or measures intended to achieve a
comparable reduction in water consumption by t he persons it serves relative to the amount
consumed in 2013.
